Abstract: FIELD: oil industry, development of inhomogeneous oil deposit. SUBSTANCE: oil in agreement with invention is recovered through production wells. Working fluid is pumped through injection wells. Suspension of water-soluble polymer in hydrocarbon liquid is injected into wells. Water-free oil is used to fill well before pumping suspension of water-soluble polymer in hydrocarbon liquid. First technological curing is conducted in the course of 20-30 h when gel of water-soluble polymer starts formation in pores of drowned part of pool. Volume of liquid equal to injected volume is extracted from well smoothly, in the course of 1.5-2.0 days. Second technological curing in the course of 20-30 h is conducted for final formation of gel of water-soluble polymer. Then well in put in production.

Abstract: FIELD: electric arc metal spraying in machine engineering, possibly applying of metal coats on hard-to-reach surfaces of articles. SUBSTANCE: electric arc metal spray gun includes housing in which flexible current supply leads combined with wire electrodes are arranged, air supply pipe and spraying device. The last is spaced from gun housing by some distance but it is connected with it by means of flexible current supply leads and air supply pipe. Such design allows to incline spray device downwards or upwards relative to housing by angle exceeding 0 degrees until 90 degrees if it is necessary to metallized hard-to-reach places. When air passes through air supply pipe the last is dilated and it is jammed in opening providing fixation of spray device in desired position. Housing of spray gun is in the form of tube or telescopic tube in order to provide comfortable use of apparatus. Electric arc spray gun may be easily transported to necessary working zone but power supply unit, mechanism for feeding wire and compressed air source are mounted stationary.

Abstract: FIELD: technique of sublimation drying. SUBSTANCE: method consists in measurement of the initial and final moisture content of product, sustaining of the sublimation pressure, measurement of consumption and temperature parameters of refrigerant, stabilization of the current value of heat flow.
